Modafinil is used to treat symptoms of
excessive sleepiness caused by such conditions as sleep apnea,
narcolepsy, or shift work sleep disorder. It is also prescribed for all
forms of excessive daytime sleepiness where causes can't be identified.

How to take:

Follow your doctor's directions, never take less or more than
precribed. Do not take this medication for longer than prescribed.
Modafinil is usually given for 12 weeks or less. The usual prescribed
dosage for these disorders is 200 mg once a day. For conditions other
than shift work sleep disorder, modafinil is normally taken in one dose
in the morning or in two doses in the morning and at midday. It is not
recommended to take modafinil after noon: taking it during the later
part of the day may cause insomnia at night.

Precautions:

Do not use this medication if you are
allergic to modafinil or armodafinil (Nuvigil). Tell your doctor if you
have chest pains, liver or kidney disorders, any heart diseases, a
history of drug addiction, if you take blood pressure medication, or if
you have recently had a heart attack. This medication impairs thinking
or reactions. If you have to do something which reuires being alert, be
careful to avoid dangerous accidents.

Side effects:

This medication may cause severe adverse effects, including severe
dermatologic reactions, serious and potentially fatal conditions such as
Toxic epidermal necrolysis, DRESS syndrome (Drug Reaction (or Rash)
with Eosinophilia and Systemic Symptoms), and Stevens-Johnson Syndrome.
The symptoms of these diseases may include fever, sore throat, headache,
and vomiting with a severe blistering, peeling, and red skin rash.
Modafinil may also have a contraceptive effect which lasts for a month
after cessation of dosage. Always consult with a specialist before
taking any medication.
